Practical Global Backprojection-Convolution in Transmission Cone-beam Computed Tomography
Murdock Grewar, Glenn Myers, Andrew Kingston
Global backprojection-convolution (GBC) is a recently developed theory for exact reconstruction in transmission cone-beam computed tomography (CBCT). It is the first exact inversio…
